The edge of the first insulating part 3202 and the edge of the second insulating part 3211 both form a closed groove 33, and when the first driving member 31 drives the first insulating part 3202 and the second insulating part 3211 to be placed in the cleaning tank 40 and rest, the third driving member 44 can drive the closing bar 43 to press against the closed groove 33 to separate the cleaning tank 40 from the housing 1. In this embodiment, for an alternative dust collection manner, the first insulating portion 3202 and the second insulating portion 3211 are stationary inside the cleaning tank 40, the discharging portion 3201 and the dust collecting portion 3210 are stationary outside the cleaning tank 40, and the closing bar 43 is pressed into the closing groove 33, so that the dust collecting portion and the insulating portion do not interfere with each other.

The self-cleaning step of the electrostatic dust removing piece comprises the following steps which are carried out in sequence:

(1) after the control support frame 30 rotates at a first speed by a first angle (specifically, the control module sends a control command to the first driving member 31, the first driving member 31 drives the support frame 30 to rotate), the control support frame 30 stops rotating and simultaneously drives the closing strip 43 to press against the surface of the discharge electrode 320 or the dust collecting electrode 321 (specifically, the control module sends a control command to the third driving member 44, and the third driving member 44 drives the closing strip 43 to move); the first speed is small in order to rotate the support 30 slowly so as to drive the closing bar 43 to press against the surface of the discharge electrode 320 or the dust collecting electrode 321 to close the insertion opening 402 (closing the insertion opening prevents the cleaning water in step (2) from being sprayed out of the cleaning tank 40 from the insertion opening 402), so that the discharge electrode 320 and the dust collecting electrode 321 are partially still in the cleaning tank 40 and are contacted by the cleaning piece 41 for treatment, and the first angle is in order to prevent the discharge electrode 320 and the dust collecting electrode 321 from being repeatedly treated each time, and the first angle are specifically required to be adjusted through test matching.

(2) Controlling the rotation of the cleaning member 41, and controlling the water discharge port 401 and the water spray port 400 to spray water to the discharge electrode 320 and the dust collecting electrode 321 in the cleaning tank 40; in this manner, the surface of the electrostatic precipitator 32, which is stationary in the cleaning tank 40, is cleaned.

(3) Acquiring the working time of the step (2) (which can be acquired by a timing circuit carried by the control module and signal transmission between the control module and the second driving piece 42), when the working time is greater than a preset threshold value of unit cleaning time, controlling the cleaning piece 41 to stop rotating, and controlling the closing strip 43 to leave the surface of the discharge electrode 320 or the dust collecting electrode 321 to open the insertion port 402;

(4) repeating the steps (1) to (3) for multiple times, that is, through multiple cycles, the surface of the electrostatic dust removing part 32 can be sufficiently cleaned, and the number of times of the repetition is recorded (the first driving part feeds back a signal to the control module in the step (1) for counting, and the second driving part feeds back a signal to the control module in the step (2) for counting), and the turbidity of the rinsing water with the discharge electrode 320 and the dust collecting electrode 321 in the cleaning tank 40 is detected (specifically, a turbidity sensor can be arranged in the cleaning tank 40 close to the cleaning part 41, and a product with signal output is selected, such as an online turbidity sensor of OSA38 manufactured by nordic electronics technologies ltd, so that communication connection can be realized); the control module acquires a turbidity value of the control module;

(5) in order to clean the electrostatic dust removal part 32 sufficiently, when the repetition times are greater than the preset repetition threshold and the turbidity of the shower water is lower than the preset turbidity threshold of the shower water (which indicates that the electrostatic dust removal part 32 is completely cleaned), the cleaning part 41 is controlled to stop rotating, and the water discharge port 401 is controlled to discharge water and the water spray port 400 is controlled to be closed;

(6) acquiring water level information in the cleaning tank 40 (a water level controller can be arranged in the cleaning tank 40, such as a single-loop intelligent digital water level meter produced by Towey company, Zhejiang, and electromagnetic valves can be arranged at the water spray opening 400 and the water discharge opening 401, and linkage control of the water level in the cleaning tank 40 is realized through the water level controller and the electromagnetic valves), when the water level in the cleaning tank 40 is lower than a preset water level threshold (specifically, the water in the cleaning tank 40 is completely discharged), controlling the hot air inlet 403 and the heating element 45 to be opened (blowing hot air into the cleaning tank 40 and simultaneously drying the electrostatic dust removal element 32), and controlling the support frame 30 to be opened (the drying efficiency of the electrostatic dust removal element 32 can be accelerated);

(7) humidity information in the cleaning tank 40 and the housing 1 is acquired (a humidity sensor can be installed in the housing 1), and when the humidity values are lower than a preset humidity threshold value, the support frame 30 is controlled to rotate at a first speed (a non-contact type rotation speed sensor can be installed on the support frame 30, and an output signal can be a pulse signal and processed into a digital signal by using an operation conversion circuit and transmitted with control module information so as to control shutdown).

The shutdown control procedure is to obtain the positions of the first insulating part 3202 and the second insulating part 3211 (a non-metal proximity sensor may be disposed in the cleaning tank 40 near the insertion opening 402 for detecting non-metal insulating materials, such as model No. AN LL EVI, CPS-18PO 8B), control the third driving member 44 to drive the closing bar 43 to slide and press into the closing groove 33 and simultaneously control the first driving member 31 to stop working when the first insulating part 3202 and the second insulating part 3211 are both located in the cleaning tank 40, and then control the fan assembly 2 to turn off the power supply to stop working.
